Rolodex

Its name, a portmanteau of the words "rolling" and "index", has become somewhat genericized for any personal organizer performing this function, or as a metonym for a total accumulation of business contacts.

In this usage, it has generally come to describe an effect or characteristic of the small-world network[1] of a business's investors,[2] board of directors,[3] or the value of a CEO's contacts,[4] or in organizational structure.

Zephyr American also invented, manufactured and sold the Autodex, a spring-operated phone directory that automatically opened to the selected letter; Swivodex, an inkwell that did not spill; Punchodex, a paper hole puncher; and Clipodex, an office aid that attached to a stenographer's knee.

[11][12] Rolodex also marketed non-rotary (linear) tub-like card-file systems using the same cards (size and notches) as the rotary files.

A 1985 episode of the detective TV series Moonlighting involved a stolen Rolodex being ransomed for $50,000 — a figure reflecting the value of the data it contained.
